[Resolved] Upgrade path from WP 3.0 RC 1 to WP 3.0

I cannot remember the last time I used an RC1 install of WordPress so I do not remember if there is a clear upgrade path from a release candidate to an official release. So, that is my question to you, should you choose to accept it: is there a clear, upgrade path from WP 3.0 RC1 –> WP 3.0 i.e. via the one-button upgrade or the usual simple FTP file replacement path?
